I agree with you both that this sounds like a great thing to add to gnome-mag. By the way, Carlos has recently done some very nice work to enable fullscreen magnification without requiring two X screens, so based on this new work (still in bugzilla, but soon to be in cvs we hope), this could be done pretty elegantly at "1:1" without noticeably changing the user experience. Best regards Bill p.s. - gnome-mag magnifies at '1x' if you run it with "-z1". To use this in fullscreen mode without changing your Xorg.conf will require Carlos' patch to http://bugzilla.gnome.org/show_bug.cgi?id=348375. Henrik Nilsen Omma wrote: |
